How To Clean Sealer Off Tiles ?

There are a number of ways in which the problem might be rectified, depending on the circumstances.

For example, if a solvent sealer was used, it is sometimes possible to use a little more of the actual sealer, the solvent carrier-fluid it contains can sometimes re-dissolve the residue allowing it to be wiped away with an absorbent cloth.

For other residues, the use of Nanoscrub is recommended. First apply a little water to the affected area, and then add a little Nanoscrub and scrub. Rinse well and dry down with paper towels. For really stubborn or thick residues that have been left for some time, a stripper may be required. In such situations use a Sealer & Coating Remover, applied neat and left on for a minimum of 30 minutes before scrubbing with a white nylon pad.

Apart from the last remedy (using a stripper) the others should not result in the need to re-apply more sealer afterwards. So, it need not be the end of the world if a sealer residue is left on the surface, but it is of course better to avoid the problem altogether, by applying the sealer correctly in the first place.

I have porcelain tile on my floors - they have a sealer over the entire floor.  It shows scuff marks and marks from a pad that I put under my area rug.  How do I get this sealer off the floor?  I know I will need to reseal the grout lines.  I have tried fingernail remover - what else is there?
